Abstract

PURPOSE: To propose the suspension structure of a vibration damping device in a cableway transporter, suitable in the case of providing the cableway transporter with the vibration damping device. CONSTITUTION: In a cableway transporter 1 formed by suspending a passenger car 20 through a suspension hanger 10 from a suspension means such as a cable gripper 3 for gripping a cable 51, a vibration damping device 30 is suspension-fitted to the bottom face 24 of the passenger car 20 in an attitude effective in the right-angled direction to the proceeding direction of the passenger car 20. The vibration damping device 30 can thereby be installed without protruding from the upper vehicle limit of the transporter 1, and there is no fear of getting close to or coming in contact with transporter operating equipment. Since this fitting position is offset from the center-of-gravity position of the transporter 1, the vibration damping function of the vibration damping device 30 acts effectively so as to be able to obtain excellent vibration clamping effect.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension structure of a vibration damping device in a cable carrier for operating a carrier in which a passenger car is suspended by a suspending means suspended from a rope through a suspending hanger.

[0002]

2. Description of the Related Art In a cableway facility for transporting a carriage by suspending a passenger car through a suspension hanger, a rope means is used as a suspending means. A group of single-line automatic circulation cableway, single-line fixed circulation cableway, etc. of a type that detachably or semi-permanently uses a gripping machine to support and tow a carrier with the rope,
A group of crossing cableways, double-track or three-line circulation cableways, in which a carrier is supported by using a traveling machine that rolls a rope as a suspending means, and the carrier is towed by a separate traction means.
There is.

[0003] These are equivalent in that they are collectively bundled as cableway equipment, and in each case, the carrier is suspended on the rope by a suspending means such as a gripping machine or a traveling machine. In the present application, any of these types of cableway equipment are also suspended. It is included.

In these cableway facilities, the carrier is typically regarded as a simple pendulum having the rope position or the position of the suspending means as a suspension fulcrum, and does not roll when strong winds are received due to a crosswind. Rocking easily occurs, which is a weak point of cableway equipment. When such a roll occurs, not only does the passenger feel discomfort or anxiety due to the rocking, but also it is often forced to be suspended to prevent danger, which has been a safety and economic problem due to suspension. Furthermore, recently, the cableway equipment is intended to be used not only as a conventional tourist equipment for mountainous areas but also as a general transportation equipment for regional transportation. The desire is increasing.

In response to such a demand, as a vibration damping device or method for a carrier, a structure in which a gyro is mounted on the carrier or a structure using a passive type vibration absorption or vibration damping device such as a pendulum type has been proposed. There is.

Regarding the former, for example, Japanese Unexamined Patent Publication (Kokai) No. 5-87183, “Vibration Control Device” has been proposed.
However, in this device, although a power source is required for the electric motor for gyro rotation, in general, it is extremely difficult to request the power source to the outside of the cableway carrier, which is a practical problem.

On the other hand, as a device using a passive type vibration damping device, for example, Japanese Patent Application No. 1-163632 “Structural vibration damping device”, Japanese Patent Application No. 3163/1999 filed by one of the applicants of the present application. No. 10760 "Structural damping device", etc., has already been disclosed a damping device that supports a weight so that it can move along an orbit formed in an almost arc shape so as to perform single string vibration. Although it has been put to practical use in structures,
Further, in the “sway stop device” filed by the applicants of the present application on January 19, 1995, the damping body is guided by a substantially arcuate rail upward and the damping body is self-propelled, Passive type vibration damping devices have been proposed which try to suppress vibrations by compensation.

This device can achieve its purpose with a relatively simple structure and does not require a power source, so that it can be suitably used for a cableway transporter in which it is difficult to obtain a power source.

[0009]

However, the suspension means of the cableway carrier, in particular, the suspension means such as a gripping machine and a traveling machine, and the suspension hanger and the like are stopped at a stop through which the carrier is operated.
Various mechanical equipments, supporting structures, etc. necessary for operation are arranged at each point of the cableway, etc., and it is necessary for the carrier to be configured so that it can pass without interference with these and without trouble. Therefore, even when an additional device such as a vibration damping device is provided, there is a constraint condition that it should be kept within the vehicle limit so as not to interfere with these.

In response to such a situation, the present invention aims to propose a suitable and effective suspension structure for a vibration damping device in a cable carrier that satisfies the constraint conditions for mounting without impairing the vibration damping performance of the vibration damping device. It was made as.

[0011]

To this end, the present invention comprises a suspension means for suspending a transporter on a line, and a vibration damping device for the transporter for suspending a passenger car through a suspension hanger. The vibration damping device uses a passive vibration damping device of a type in which a traveling body is self-propelled by being guided to a guide rail surface having an upwardly concave substantially arcuate shape. A suspension structure of a vibration damping device in a cable carrier, which is suspended from the bottom of the passenger car in an effective posture in a direction perpendicular to the direction of travel of the carrier.

[0012]

The vibration damping structure for a cable carrier of the present invention includes a vibration damping device for a cable carrier that suspends a passenger car through a suspension hanger on a suspension means such as a gripping machine or a traveling machine for suspending the carrier on a line. It is a suspension. The vibration damping device uses a passive vibration damping device of a type in which the traveling body is guided by a guide rail surface that is concave upward and has a substantially arcuate shape, and the traveling body self-propels. In the present invention, the vibration damping device is provided by suspending it on the bottom surface of the passenger car in an effective posture in the direction perpendicular to the traveling direction of the carrier. For cableway equipment, various devices, structures, etc. are provided near the upper part of the cable carrier, suspension hangers, etc. near the upper part of the cable carrier in order to operate the cable carrier. Although there are restrictions on the mounting position of the additional object, in the structure of the present invention, since the additional installation is not performed on the upper portion of the passenger car, there is no risk of interference, etc., and safe operation can be performed. In addition, there is no risk of reducing passenger comfort without reducing the passenger space.

The center of gravity of the carrier that rolls and swings around the position of the rope or the suspension means as a suspension fulcrum varies slightly depending on the presence or absence of passengers in the passenger car, but generally within the area of the passenger car and in the passenger car. It is said that the natural frequency of the carrier is determined by the length of the arm between the fulcrum and the position of the center of gravity. On the other hand, it is effective to install this damping device at a position that does not match the center of gravity of the carrier, but the vibration damper installation position near the bottom of the passenger car does not match the center of gravity of the carrier and is below the center of gravity of the carrier. Therefore, the vibration damping effect of the vibration damping device works effectively. Moreover, the damping device used in the present invention has a feature that the natural frequency of the damping device can be easily selected by adjusting the radius of curvature of the substantially arc-shaped orbit. By selecting the one having a suitable vibration damping characteristic corresponding to the mounting position, it is possible to enjoy an effective vibration damping action.

To be equipped with. In this embodiment, a cover 45 for covering the vibration damping devices 30, 30 from below is provided on the bottom surface 24 of the passenger car 20 to cover the vibration damping device 30 to improve the appearance.

It should be noted that, depending on the weight of the carrier and the size of the required vibration control condition, a plurality of vibration control devices 30 may be similarly mounted by suspending a plurality of vibration control devices, or if a single vibration control device is sufficient. Of course, such a selection is also possible.

Next, the operation or action of the vibration damping device for a cable carrier according to the present embodiment thus constructed will be described.

The present embodiment shows the case of the single-track automatic circulation type cableway 50, and the suspension means 2 is the gripping machine 3 as an example.
Operates as shown in FIG. 5, as is well known. That is, the rope 51 is wound endlessly between the pulleys 53, 53 pivotally installed at the stops 52, 52 at both ends and stretched in the cableway 56. The rope 51 is guided and supported in the cableway line 56 by pressure receiving cable devices 59, 59 provided on a column arm 58 of a column 57. At the stop 52, the carrier 1 is equipped with the gripping device 3 and guided by the forwarding rail 54 to roll on the traveling rollers 7. When the carrier 1 leaves the stop 52, the rope 51 is gripped by the gripping machine 3, and the carriage 51 is circulated and pulled by the rope 51 to carry the carrier. When the carrier 1 reaches the other stop 52 of the other party, the gripping of the gripping machine 3 is released, and is separated from the rope 51 and guided again to the forwarding rail 54 to be transferred and transferred, and the return operation is performed in the direction of the cableway line 56. Are carried out, and thus the plurality of transporters 1, 1 ... Are cyclically operated one after another.

In such an operation mode, the carrier 1 is a machine necessary for the operation of the carrier 1 when the carrier 1 is being transported to the inside of the stops 52, 52 or being operated on the cableway 56. Since it passes in close proximity to the device and the supporting structure, protruding appendages exceeding the predetermined vehicle limit are not allowed, however, in this damping structure, the damping device 30 is suspended on the bottom surface 24 of the passenger car 20. Since it is equipped, there is no protruding appendage on the upper part of the carrier, and there is no risk of abutting or interfering with external devices.

The mounting relationship of the vibration damping device 30 is as described above. Even with such mounting and mounting relationship, the damping performance of the vibration damping device 30 is sufficiently exhibited as follows. . That is, the center of gravity of the carrier that rolls and swings with the position of the rope or the suspension means as the suspension fulcrum varies slightly depending on the presence of passengers in the passenger car, but it is generally within the area of the passenger car and the passenger car. It is said that the natural frequency of the carrier is determined by the length of the arm located near the center of the carrier and between the fulcrum and the position of the center of gravity. on the other hand,
This vibration damping device is effective in terms of vibration damping provided at a position that does not match the center of gravity of the carrier, but the mounting position of the passenger car bottom surface is sufficiently deviated at least below the center of gravity, Therefore, the damping effect of the damping device is effectively exhibited. In addition, since the vibration damping device used here has a feature that the natural frequency of the vibration damping device can be arbitrarily selected by adjusting the radius of curvature of the substantially arc-shaped orbit. By selecting the one having a suitable vibration damping characteristic corresponding to the mounting position, it is possible to enjoy an effective vibration damping action.

In the above explanation, the case of the automatic circulation type cableway using the automatic gripping machine for gripping and releasing the cord as the suspending means is explained. However, the carrier is suspended on the two parallel cords. In the case of a double-type single-line automatic circulation cableway that operates as a single line or in the case of a type of cableway equipment that performs cyclic operation or alternate operation with movement of the rope using a fixed type gripping machine that semi-permanently grips the rope. However, it is needless to say that the vibration damping structure described in the present embodiment can be similarly configured and the functions and effects are equal.

Alternatively, instead of the gripping rope as the suspension means, a traveling machine that is guided by a line and rolls is used, and a so-called crossover cableway that is separately pulled and operated by a tow line as a pulling means. Even in the case of equipment and the like, the manner of swinging with the rope position or the position of the suspension means as the suspension fulcrum is completely equal. Therefore, even in the case of such a type of cableway equipment, the above-mentioned configuration is similarly applied and the same effect can be obtained.

[0032]

EFFECT OF THE INVENTION Suspending means for suspending a carrier on a cord,
That is, cableway equipment that transports by carrying a carrier that suspends a passenger car through a suspension hanger using a gripping machine or a traveling machine is economically constructed compared to other transportation means. It has various features such as being able to do and being able to run on steep slopes. However, the cableway equipment is typically regarded as a simple pendulum with the position of the rope or the suspension means as the suspension fulcrum, and there is a weak point that it tends to roll in the case of strong winds, and improvement is desired. It was

In response to such a request, a method of mounting a gyro on the carrying device has been proposed, but it has a drawback that the carrying device needs to be powered.

On the other hand, according to the present invention, the passive type vibration damping device previously proposed by the applicants of the present invention is used to suspend the vehicle on the bottom surface of the passenger car in an effective posture in the direction perpendicular to the traveling direction of the carrier. The present invention proposes a suspension structure for a vibration damping device of a cableway carrier that can be suitably used for the cableway carrier.

According to the above-described suspension structure of the present invention, the vehicle limit is violated because it is mounted so as not to project outside at a position above the carrying device that passes close to a mechanical device or structure for operating the carrying device. It is possible to install a vibration control device.
Also, by covering the vibration damping device with a cover or the like, the appearance is not impaired. In addition, it does not protrude into the passenger space in the passenger car and does not impair the comfort of the passenger. Moreover, there is an advantage that a power supply to the carrier is not required, and therefore, it can be applied relatively easily not only when applied to a new cableway equipment but also when additionally installed to an existing cableway carrier.

From the viewpoint of vibration damping performance, it is effective to provide this vibration damping device at a position that does not coincide with the center of gravity of the carrier, but the mounting position on the bottom surface of the carrier does not coincide with the center of gravity of the carrier. Therefore, the damping effect works effectively. In addition, this damping device has a feature that the natural frequency of the damping device can be easily selected by adjusting the radius of curvature of the substantially arc-shaped orbit. By setting a suitable vibration damping characteristic, it is possible to enjoy the optimum vibration damping action for the carrier and it is effective for safe operation of the cableway during strong winds.
